Naiad, Moon of Neptune

Naiad is a Moon that orbits round the planet Neptune. Its mass is estimated/calculated at being 194,826,896,302,635,000 kg. Its density has been calculated at being 1.3. Its volume is 150533.

It was discovered in the year 1989 by Voyager 2.

The orbital period, i.e. the period it takes to complete an orbit round Neptune is 0.2944 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Equatorial Radius of the object is 33km. The value is the radius in km of the said object at the Equator.

The Escape Velocity of the object is 101 km/h. The Escape Velocity is the speed an object needs to be travelling in order to break free from the objects gravity. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 48.227, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Naiad is 207.3 km. The surface area of Naiad is 13,684.78. The surface gravity of the said item is 0.012. The Mean orbit velocity, that is the speed at which it orbits is 42944.90 km/h. The is the average distance in km of the object is from its parent 48227.00.

The orbital inclination, the angle at which Naiad orbits in relation to the orbital plane is 4.74 degrees. The orbital eccentricity is 0.0003, it is the degree at which Naiad orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
